GRAlN-DRILL AND SEEDER.

SPECIFICATION forming part. of

Letters Patent No. 369,383, dated September 6, 1887.

Application filed November 27,1886. Serial No. 220,051. (No model.)

To (tZZ whom it may concern.-

Be it known that I, WILLIAM D. Annnrr, of Denver, in the county ofArapahoe and State of Colorado, have invented certain Improvements inGrain'Drills and Seeders, of which the following is a specification.

My invention relates to that class of graindrills and seeding-machinesin which the furrow-opening devices are carried by a series of drag-barsjointed to a wheeled frame and arranged to rise and fall independently,and has reference more particularly to improved means for applyingdownward pressure to said bars.

The improvement is designed for usein connection with those machines inwhich furrowopening disks are applied, two to each dragbar, asrepresented, for example, in my applications forLetters Patent of theUnited States filed, respectively, on the 5th day of April, 1886, SerialNo. 199,137, on the 22d day ofMay, 1886, Serial No. 203,029, and on the30th dayof July,1886, Serial No. 209, 547, but is also'applicahle tomachines in which tubular hoes are used in the ordinary manner.

The improvement consists in a peculiar arrangement of weights andequalizing-levers, through which the pressure is applied equally to theseveral drag-bars, as hereinafter described.

Beferring to the accompanying drawings, Figure 1 is a perspective viewillustrating my invention in its most simple form, the weight actingupon two drag-bars. Fig. 2 is a rear elevation of the same, three of theweights being shown, each in connection with two dragbars. Fig. 3 is aside elevation in outline of the machine. Fig. etis a rear elevationshowing a single weight used in connection with four drag'bars.

\Vith the exception of the parts hereinafter specifically described, theentire machine may be of ordinary construction. I have omitted from thedrawings the hoppers, the feed mechanism, and the various othercustomary parts which are foreign to my invention.

Referring to the accompanying drawings, A represents the wheeled mainframe; B B, the series of drag-bars jointed at their forward ends to theframe, and O O furrow-opening disks, usually applied two to each bar.These parts may be identical with those represented in either of myprior applications.

In applying my improvement in its preferred form I connect to or mountupon the rear end of each drag-bar an upright rod, i), playing at itsupper end loosely in a suitable guide on the frame. hen the weight is tobe applied to two drag-bars only, I turn the upper ends of the two rodslaterally, as shown in Figsl and 3, and by means of links or otherconnections suspend a bar or lever, E, at its two ends from therespective rods. From the center of this bar I suspend a weight, F,which may be a metal block of suitable size and form, or, as shown inthe drawings, a block-like receptacle, into which weights of anysuitable character may be placed.

It will be observed that the lever E acts as an equalizing device,distributing the weight between the two rods D, which act with adownward pressure on the drag-bars, allowing each to rise and fallwithout affecting the other. When a single weight is to be used withfour bars, I apply the levers E, as above described, instead ofconnecting the weight directly to said levers. I employ asccond lever,G, suspended at its ends from the middle of the levers E, and providedat its own middle with the weight F.

I am aware that a single weighted lever has been combined with a seriesof intermediate levers acting on the forward ends of a series ofdrag-bars, and this I do not claim.

What I do claim is- 1. In a seeding-machine, a wheeled frame and aseries of drag-bars jointed at their forward ends thereto, incombination with a series of upright rods, connected at their lower endsto the respective drag-bars and arranged to slide at their upper endsthrough guides on the frame, a weight, and an equalizing lever or leversconnecting said weight with two or more of the rods, as described.

2. In a seeding-machine, the combination, with the main frame and aseries of drag-bars jointed thereto, of the series of equalizin leversconnected with the respective dragbars, and a box-like receptaclesuspended from said levers and adapted to receive weights, as describedand claimed.
